  text: "We analyse an InAs/GaAs-based electric field tunable single quantum dot diode
    with a thin tunnelling barrier between a\r\nburied n þ -back contact and a quantum
    dot layer. In voltage- dependent photoluminescence measurements, we observe rich
    signatures from spatially direct and indirect transitions from the wetting layer
    and from a single quantum dot. By analysing the Stark effect, we show that the
    indirect transitions result from a recombination between confined holes in the
    wetting or quantum dot layer with electrons from the edge of the Fermi sea in
    the back contact. Using a 17 nm tunnel barrier which provides comparably weak
    tunnel coupling allowed us to observe clear signatures of direct and corresponding
    indirect lines for a series of neutral and positively charged quantum dot states."
